I’ve a Barth breakaway. The Atwood hot water heater is a CH6-6E and is working but requires a new gas valve. ( sticking) Since I don’t know the vintage of this hot water heater unit, I was considering a replacement. The -6E seems obsolete so my question is, what is the next step or equivalent? IE; the -8E ? Does anyone have a breakdown on what the designations mean?
Thanks!

It may be a lot cheaper to replace the gas valve. Chances are it is still being produced. Really only 2 choices: pilot style and electronic spark style. These things have aluminum tanks and rarely corrode through.

Search for CH6-6E shows gas valve part number 93844 available:

Easy to change.

For about $60 more you can rebuild everything except circuit board. I did my 10 gallon Atwood a while back.

The new model numbers are indeed confusing.

Your choices include LP only, LP + 110V, and LP + 110V + engine heat. LP models with pilot may require no power. Those models with spark ignition will require 12V to power the ignitor circuit board.

Why not upgrade to an on demand water heater?

If it were you Steve you would buy 2 and keep one as a spare.

Nothing beats a long hot shower.

Why do we need a hot water heater anyway? If it's already hot it doesn't need heating!

A cold water heater, now that could be handy…
